P3466 OBD Error Code: Problem & Solutions

<<See All OBD Codes

Stressed? Don’t know what to do to treat the error code P3466? Well, we have listed all that you need to know about the error code P3466. For maximizing the fuel economy, the engine should duly be protected from excessive stress and the emissions should be reduced too. When the vehicle is operating under light load conditions, the latest model vehicles with more eight or more cylinders feature a deactivation process that turns off half of the cylinders. The ECM is informed by the MAF (mass air flow), MAP (manifold absolute pressure), and TP (throttle pressure) sensors to turn off the fuel injectors to certain cylinders. The intake valve that offers fuel to the engine doesn’t shut down as per the requirements, if the cylinder 9 fails to operate. The error code P3466 is stored as soon as the ECM receives a message about the failure.

This generic OBD-II code decreased engine performance is also described as a cylinder 9 deactivation/intake valve control circuit performance. For achieving the fuel and emission standards, a number of manufacturers’ make use of the cylinder deactivation systems. At times, when additional power is not needed (such as idle or cruising), this system allows the engine control module (PCM) to deactivate the select cylinders. If the intake valve for cylinder number nine fails to turn on or off the way is required to, the engine control module determines that and the PCM sets the error code P3466.

What causes this problem with the Cylinder 9 Deactivation/Intake Valve Control Circuit Performance?

• Malfunctioning sensor (mass airflow sensor or manifold absolute pressure sensor)
• Defective deactivation solenoid
• Short circuited wiring or harness
• Bad fuel pressure
• Damaged valve lifter
• The oil pressure is low
• Open deactivation solenoid connection
• A mechanical defect in the engine

1. Powertrain Control Module - Diminishing engine performance, unexplained drops in the fuel economy and also problems in shifting the gears when in transmission are some basic issues that follow a failure in the powertrain control module. Tune into Parts Avatar if you want to get rid of these problems caused by the error code P3466.
2. Exhaust Valve - A distorted exhaust valve can end up being the chief host inviting the error code P3466. Not only this you are likely to observe unexplained inconsistencies with the exhaust system too. So replacing one can be one of the wisest decisions to avoid a problematic system.
3. Mass Airflow Sensor - Is your engine hard to turn over or start? Well, then this is indicative of a fault in the MAF sensor. Get it repaired or replaced immediately.
4. Manifold Absolute Pressure Sensor - Insufficient power? No acceleration in the vehicle? Difficulty to maintain an optimum fuel efficiency? We recommend you to change your manifold absolute pressure sensor immediately if you wish to avoid the problems caused by the error code P3466.
5. Intake Valve - Check engine light flashing on? Engine not idling smoothly? Car accelerating but not exceeding a relatively low speed? Well, all of it is triggered due to a fault in the intake valve. Tune into Parts Avatar for your new intake valve.
6. Exhaust Valve - A malfunctioning exhaust valve can be troublesome. Apart from the error code P3466, it also leads to a difficulty starting the vehicle and loss of power. Log into Parts Avatar for top notch exhaust valve offered at budget friendly prices.
7. Engine Oil - Excessive mileage? Well, then in that case you should change your engine oil instantly. Visit us today to grab some of our amazing offers.
8. Engine Control Module - Abbreviated ECM; this is an integral control unit. So, a malfunctioning one should be changed immediately, if you want to avoid problems with the engine stalling, rough idles and sudden falls in the economy. Tune into Parts Avatar.

It is vital to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD code P3466 here:

Common Symptoms

• Engine misfiring
• Bad fuel economy
• Decrease in the engine performance
• The service engine soon light flashing
• Check engine light flashing

Want to correct the trouble code P3466? Read these points mentioned below:

• Replacement or repairs should be performed of a malfunctioning cylinder 9 deactivation solenoid
• All the corroded or damaged wiring or connections should be mended or restored
• Make sure you repair or replace a valve lifter that is defective
• Ensure that a thorough cleansing of oil passages is performed immediately, if required

Here are some steps which you should follow in order to diagnose this fault code:

To begin with, the technician should ensure presence of accurate oil and pressure levels. Then the DTCs should be checked using a scanner. These codes along with the ones stored in the powertrain control module should be analyzed and diagnosed using the scanner. Then clear the codes from the scanner. Then move on to probing the cylinder deactivation solenoid using a scan tool. The oil passages should be inspected and the debris (other obstructions too) should be cleared. Malfunctioning valve lifters should be suspected if the technician assures that the solenoid is functioning as per the requirements and there aren’t any oil blockages too.

Common Mistakes When Diagnosing the P3466 Code

Here we have listed all the mistakes that should be avoided:

• Low engine oil level
• Failed powertrain control module (PCM)
• A fault in the variable valve timing solenoid
• Wiring problems
